Cull crocs or we'll block Qld budget: KAP

MPs from Katter's Australian Party are threatening to block the upcoming state budget if the Queensland government doesn't back their proposal to cull crocodiles.

Mt Isa MP Robbie Katter and fellow KAP MP Shane Knuth say they will block the budget unless the government supports their bill to establish crocodile safaris in far north Queensland, along with other management strategies.

"People think it's unreasonable making threats on the budget, well how else do you get people to listen?" Mr Katter said in Cairns on Wednesday.

"Our obligation is to go down there and vote for the interests of north Queensland, and if people are dying and you can't get them to listen, what are you supposed to do?"

But Premier Annastacia Palaszczuk has maintained her government's policies were working in regards to managing the crocodile population despite acknowledging the reptiles' numbers were increasing.

"The department of environment is working very closely to remove those problem crocodiles as fast as they can," she said.

It follows a number of recent incidents involving crocodiles in Queensland.
